Instruction cycle in microcontroller
Nettet[1] Branches take one cycle for instruction and then pipeline reload for target instruction. Non-taken branches are 1 cycle total. Taken branches with an immediate are normally 1 cycle of pipeline reload (2 cycles total). Taken branches with register operand are normally 2 cycles of pipeline reload (3 cycles total). Nettet19. okt. 2015 · In the execution cycle, the fetched instruction is latched into the Instruction Register (IR) in cycle Q1. This instruction is then decoded and executed during the Q2, Q3 and Q4 cycles. Data memory is read during Q2 (operand read) and written during Q4 (destination write).
